Show HN: MakeACopy – An offline, open-source document scanner for Android

After building Let’s Bend, a small open-source harmonica training app that surprisingly reached #1 on HN, I wanted to create something completely different - a document scanner that works fully offline. MakeACopy is an open-source document scanner app for Android that runs entirely on-device. No accounts, no ads, no tracking, no cloud - just local processing. It uses OpenCV + ONNX for document detection and Tesseract for OCR, then exports PDFs with an embedded searchable text layer (or plain text). Main features: – Detect and crop documents using OpenCV/ONNX – Local OCR via Tesseract (no servers) – Export as searchable PDF or plain text – 100 % offline, privacy-friendly, open source (Apache 2.0) Compared to apps like Adobe Scan or Microsoft Lens, MakeACopy doesn’t require an account and avoids any cloud upload.
